The Series 699 Differential Pressure Indicators & Transmitters are designed for use with air and neutral gases and are available in three configurations and several pressure ranges. Series 699 Indicators/Transmitters measure low differential pressures typically found in air conditioning applications such as in air flow measurement, fan static pressures, and specialty room pressure measurements. The series incorporates ceramic fulcrum lever technology and long set point stability, and they deliver adjusted and temperature compensated sensor signals. Configuration 1 is a transmitter with field selectable ranges and factory preset output signal and zero offset configurations. Configuration 2 incorporates a 10-position DIP switch allowing field selection of range, output signal, and response time. Configuration 3 is designed with an LED display and full-field function programming via programming button.
